Definitions

  • the present invention relates generally to a vehicle seat having an inflatable airbag contained therein and in particular to a trim cover for the seat having a reinforced region adjacent the airbag with a weakened zone forming a tear line for deployment of the airbag through the trim cover.
  • a class A airbag deploys from a visible, discreet door in the seat.
  • a class B airbag is disposed beneath the seat trim cover and is designed to deploy through the trim cover without the use of a visible door.
  • An advantage of a class A airbag with the visible door is that deployment of the airbag through the door uses technology that has already been developed for front crash airbags mounted in steering wheels and instrument panels. The technology for providing consistent and repeatable deployment of the airbag through such a door is well developed.
  • a class B airbag is often preferred for styling considerations.
  • a disadvantage of a class A airbag is that the airbag location in the seat is generally limited to the side or rear of the seat so that the visible door is not part of the seating surface engaged by a seat occupant. If it is desired for an airbag to deploy through a front corner of the seat back, such as the bolster area, it may not be possible to use a class A airbag since the door may interfere with the seating surface of the seat. Rather, class B airbag must be used in which the airbag is underneath the seat trim cover and typically covered by a foam pad so that it does not adversely impact the seat comfort. However, with a class B airbag, there are considerably more variables involved with providing consistent airbag deployment and in meeting the desired airbag in-position timing.
  • the seat trim cover provides numerous variables effecting airbag deployment.
  • the trim cover type such as cloth, vinyl, leather, etc., and combinations of these various types all behave differently and have different tensile and tear strength.
  • different materials of the same types such as different woven fabrics have different tensile strengths, tear strengths, weave nap direction, etc. which can effect the manner in which an airbag deploys through the trim cover if the airbag deploys by rupturing the trim cover.
  • Other variables introduced by the trim cover include the strength of the trim cover scrim layer or backing, and the strength of the thin layer of foam that is typically laminated to the underside of the trim cover outer layer.
  • One approach to reduce some of the variables caused when deploying an airbag through the trim cover is to deploy the airbag through a seam in the cover rather than rupturing the cover material itself, as shown in the EP 0 709 429 reference (on which the preamble of claims 1 and 16 is based), the EP 0 782 944 reference, and the EP 0 768 215 reference.
  • the seat upholstery in the area over the airbag module is provided with tear seams such that the inflating cushion will burst through the upholstery.
  • the side air bag device is imbedded in a seat side portion for expanding an airbag by rip-opening a sutured portion of the seat skin material by virtue of the expansion pressure of the air bag.
  • a front seat surface layer and a side seat surface layer are sewn together using a sewing thread at a seam.
  • the seam is located at a position roughly facing the perforation of the lining member, such that the seat surface layer instantaneously ruptures at the seam when the air bag deploys. While this approach of seam deployment reduces variability, it limits seat styling by dictating where the seam is located.
  • the trim cover employs a reinforcement in the region of the trim cover overlying the inflatable airbag.
  • the reinforced region has a weakened zone forming a tear line for directing deployment of the airbag through a predetermined location in the trim cover.
  • the trim cover is shielded or protected from the inflation forces except for the weakened zone forming the tear line.
  • This tear line thus becomes the "weak link" in the trim cover, resulting in the trim cover rupturing at the tear seam as oppose to other nearby locations.
  • the trim cover is reinforced by the provision of a layer of sheet material to the inner side of the trim cover forming a reinforcing panel.
  • the reinforcing panel has a higher strength and is less stretchable than the outer surface layer of the trim cover.
  • the reinforcing panel is a low strength material compared. to the outer layer.
  • a known material for this application is the same material used in the airbag which naturally must withstand the airbag inflation forces without failure. Other high strength sheet materials may be used as well.
  • the reinforcing panel is laminated to the trim cover material. The reinforcing panel is cut along a line which may be straight or of irregular shape to provide the weakened zone in the trim cover.
  • the trim cover material has an outer surface layer and a thin layer of foam.
  • the reinforcing panel layer is positioned on the inner surface of the foam layer.
  • the tear line is preferably formed by cutting both the reinforcing panel and through the foam layer.
  • One method of manufacturing the trim cover is to first laminate the outer layer, foam and reinforcing panel to one another and then laser cut the reinforcing panel and the foam layer along the tear line.
  • the laser cut may partially penetrate into outer layer material itself.
  • the cut may only partially penetrate through the foam or may only penetrate through the reinforcing layer.
  • the laser cut may penetrate partially into the outer layer, weakening it as well.
  • the layers of the trim cover are laminated together and then laser cut to form the weakened zone. It is possible to precut the various layers and then join them together with the cut lines aligned with one another.
  • the reinforcing panel may be joined to the other layers only at the perimeter of the reinforcing panel.
  • the function of the reinforcing layer is to strengthen and reduce the stretch of the trim cover in the region surrounding the tear line.
  • a high strength and low stretchable material such as airbag fabric will perform this function.
  • the same function may be achieved with a reinforcing material that is merely less stretchable than the outer layer material.
  • Such a material when cut to form the weakened zone and laminated to the outer layer, will result in the outer layer stretching more at the tear line than the surrounding area. Thus the outer layer will fail at the tear line when the airbag deploys.
  • the reinforcing layer may not need to be high strength material. As long as the combination of the reinforcing layer and the outer layer is stronger than the outer layer by itself, the combined layers with the weakened zone in the reinforcing layer will result in failure at the tear line created by the weakened zone in the reinforcing layer.
  • FIG. 1 A seat assembly according to the present invention is shown in FIG. 1 and designated generally at 10.
  • the seat assembly 10 includes a lower, generally horizontal seat bottom 12 forming a generally horizontal seating surface 14.
  • a seat back 16 extends generally upwardly at the rear end of the seat bottom 12.
  • the seat back forms an upright seating surface 18 against which a seat occupant rests their torso.
  • the seat bottom has left and right side bolsters 20 while the seat back has left and right side bolster 22.
  • the seat assembly can include an inflatable airbag at various locations such as the side bolsters of either the side bottom or seat back for side impact protection or in the seat back to protect a rear passenger.
  • the invention will be described below in connection with a side airbag mounted to the seat back in the right bolster 22.
  • the invention can be utilized at any location in the trim cover desired for an airbag to deploy therethrough.
  • the seat back 16 includes a trim cover 24 which is made of a plurality of pieces of sheet material joined together at seams such as the seams 26 and 28.
  • the number and location of the seams is determined partially by functional considerations to form a tight, form fitting trim cover and also by stylistic considerations.
  • the trim cover piece 30 which covers all or a portion of the right side bolster 22 of the seat back is formed with a reinforcing panel as described below and which has a weakened zone forming a tear line shown by the broken line 32 in FIG. 1. As described below, it will be seen that the. tear line 32 is not visible on the surface of the vehicle seat.
  • the seat back includes a frame 34 that provides the structural support for the seat back.
  • the frame supports a pad 36 such as a urethane foam pad, rubberized hair pad, etc.
  • the pad is, in turn, covered by the trim cover 24.
  • the portion of the trim cover covering the right bolster 22 is the trim cover piece 30.
  • the trim cover piece 30 is joined to a trim cover piece 38 in the front center of the seat back at the seam 28.
  • the trim cover piece 30 extends around the bolster to the rear of the seat back where it is joined to another piece of trim cover 40 at the seam 42.
  • a mounting bracket 56 attached to the frame 34 is used to mount a side airbag module 58.
  • the airbag module includes a housing 60 with one or more threaded studs 62 that pass through apertures (not shown) in the bracket 56 and are attached thereto by nuts 64 to mount the module to the bracket 56.
  • the module 58 further includes a folded airbag 70 and an inflator 68 that provides gas for inflating the airbag.
  • a thin sheet 72 covers the folded airbag and holds the airbag in place during shipping and handling of the module. The sheet 72 is designed to rupture during deployment of the airbag without affecting the airbag deployment.
  • the illustrated airbag module 58 is only exemplary of many modules that could be used with the invention.
  • the specific structure and components of the module illustrated do not form the present invention other than the provision an inflatable airbag in the seat assembly.
  • the pad 36 may or may not completely cover the airbag.
  • the pad may have a slot 59 forming a passage for the airbag through the pad.
  • FIG. 3 illustrates the trim cover piece 30 showing the tear line 32.
  • the perimeter of the trim cover has a plurality of notches 46 which are used in aligning the trim cover piece 30 with adjacent pieces of the trim cover for joining the trim cover pieces together. In addition, these notches can be used for alignment of the trim cover piece 30 within a fixture used during cutting to form the tear line 32.
  • the trim cover piece 30 is shown in greater detail in FIG. 4. In a preferred embodiment, it is constructed of three layers.
  • the first is the outer layer 48. This may be a woven fabric, leather, synthetic sheet materials such as vinyl, or other material used to form the exterior surface of the seat assembly.
  • Joined to the underside of the outer layer 48 is a thin foam layer 50.
  • the foam layer 50 provides a smooth contour to the trim cover at the transition zones and where the trim cover is wrapped around a curved surface.
  • a reinforcing panel 52 is applied to the opposite surface of the foam layer.
  • the reinforcing panel 52 is made of a flexible sheet material to conform to the contours of the trim cover. The panel is less stretchable than the outer layer 48 and may be a low stretchable material.
  • the reinforcing panel may also be a high strength material to withstand the inflation forces of the airbag 70 without rupture of the reinforcing panel.
  • a preferred material for the reinforcing panel is the same material used to manufacture the airbag such as a nylon material. However, lower strength materials may be used if the combined outer and reinforcing layers are stronger than the outer layer itself.
  • the trim cover piece 30 is formed with a weakened zoned to create a tear line 32.
  • the weakened zone is formed by a cut in the reinforcing panel 52 at the intended deployment location of the airbag.
  • the tear line 32 also extends through the foam layer 50 and partially into the outer layer 48. Penetration of 10 or 20 percent into the outer layer is believed to have no or little impact on the wear of the outer layer.
  • the depth of the cut may vary from one application to another. At one end of the range of depths, the cut only penetrates the reinforcing panel 52. At the other end of the range it penetrates through all but the outer layer and partially through the outer layer.
  • the cut in the reinforcing layer may be a continuous cut as shown in FIG. 3 or it may be a series of short, spaced apart cuts along a line 32' as shown in FIG. 5.
  • the partial penetration into the outer layer may also be a continuous cut or short, spaced cuts as well.
  • the reinforcing panel may have a continuous cut while the outer layer has a series of short, spaced apart cuts.
  • the airbag inflates, it rapidly increases in volume and pushes outward on the trim cover.
  • the outward push of a trim cover is somewhat uniform in the area surrounding the tear line 32. Since the edges of the trim cover piece 30 are joined to the seat, the outward force F will cause tension in the trim cover piece shown by the arrows T. This will cause stretching of the trim cover until the trim cover ruptures enabling the airbag to penetrate therethrough.
  • the presence of the reinforcing layer 52 which is less stretchable than the outer layer, prevents, or at least, reduces stretch in the outer layer 48 except in the region of the outer layer overlying the tear line 32. This area will receive the maximum degree of stretching, resulting in rupture or tearing of the trim cover at the line 32.
  • the trim cover piece 30 is first formed by laminating the reinforcing panel 52 to the foam and outer layers.
  • the tear line 32 is subsequently formed by laser cutting.
  • the trim cover piece 30 is placed in a fixture to hold it in place whereby the laser cut can be controlled as to its location and depth. It is also possible to manufacture the trim cover piece 30 by first cutting the reinforcing panel 32 and the foam 50 and then laminating the layers together with the cut lines aligned with one another. Pre-cutting each layer may facilitate the cutting by allowing other cutting methods to be used. It does add complexity to the process since proper alignment of the cut lines must be maintained when the layers are joined together.
  • the foam layer 50 is optional.
  • the reinforcing layer 52 can be placed directly against the outer layer 48. Alternatively, the reinforcing layer 52 may be placed between the outer layer 48 and the foam layer 50. Other layers may be included in the trim cover piece 30 as desired.
  • the reinforcing layer is referred to as an "inner reinforcing layer" in the claims to designate that the reinforcing layer is inside the outer layer of the trim cover. There may be other layers yet inside of the reinforcing layer and between the outer layer and the reinforcing layer.
  • the multiple layers of the trim cover are laminated to one another, it is possible to form the trim cover by joining the reinforcing panel to the outer layer only at the perimeter of the reinforcing panel, such as at the seams 28 and 42 as shown in FIG. 2. With such a construction, the reinforcing panel would still function to reduce the stretching of the outer layer at locations other than the tear line 32. Preferably the reinforcing panel extends between two of the attachments of the trim cover to the seat. The piece 30 is attached to the seat wire 47 at the seam 28 and to the frame 34 at seam 42.
  • the reinforcing panel has been shown as being the same size as the outer layer of the piece 30 of the trim cover. It may be possible to use a reinforcing panel which is smaller, such as a strap, covering the region overlaying the airbag and possibly extending to the adjacent trim cover tie down locations.
  • the invention provides for a predictable and repeatable deployment of an airbag through the seat trim cover. This is accomplished by providing a reinforcing panel in the trim cover in a region overlying the airbag module. A weakened zone is formed in the reinforcing panel to form a tear line through the trim cover.
  • the reinforcing panel is made out of a material that is less stretchable than the outer layer.
